This PR makes it so type resolution falls back to looking for definitely
typed packages (`@types/foo`) if a given NPM package does not contain
type declarations.
One complication is choosing _which_ version of the `@types/*` package
to use, if the project depends on multiple versions. The heuristic here
is to try to match the major and minor versions, falling back to the
latest version. So if you have
```
@types/foo: 0.1.0, 0.2.0, 3.1.0, 3.1.2, 4.0.0
foo: 3.1.0
```
we would choose `@types/foo@3.1.2` when resolving types for `foo`.
---
Note that this only uses `@types/` packages if you _already_ depend on
them. So a follow up to this PR could be to add a diagnostic and
quickfix to install `@types/foo` if we don't find types for `foo`.
Shows directory import and missing extension suggestions in error
messages similar but not exactly to node.

Reduces some allocations by accepting either a pathbuf or url for the
referrer for resolution and returning either a pathbuf or url at the
end, which the caller can then convert into to their preferred state.
This is about 4% faster when still converting the final result to a url
and 6% faster when keeping the result as a path in a benchmark I ran.
Ensures a dynamic import in a CJS file will consider the referrer as an import for node resolution.
Also adds fixes (adds) support for `"resolution-mode"` in TypeScript.
* cts support
* better cjs/cts type checking
* deno compile cjs/cts support
* More efficient detect cjs (going towards stabilization)
* Determination of whether .js, .ts, .jsx, or .tsx is cjs or esm is only
done after loading
* Support `import x = require(...);`
